The waste heat boiler has advantages in the subdivided industry and is the leading enterprise in the industry. The company's main products are various types of waste heat boilers, industrial boilers, power station boilers, nuclear power equipment and power station auxiliaries. It is a research, development, design and manufacturing base for waste heat boilers with large scale and complete varieties in China. Beijing Full automatic fuel oil steam generator Waste heat boiler is a typical energy-saving and emission reduction equipment. Its heat source can come from high-temperature flue gas waste heat, chemical reaction waste heat, combustible waste gas waste heat, and even can use high-temperature product waste heat. At present, the company has more than 20 series and more than 100 varieties of waste heat boiler products, which are widely used in steel, building materials, power, nonferrous metals, coking, chemical and other industries. small-scale Full automatic fuel oil steam generator how much In 2008, the company produced 272 sets of waste heat boilers of various types, with a total of 10268 steam tons, accounting for 34% of the comprehensive market share based on steam tons; According to the output value, the market share is 47%, ranking first in the waste heat boiler industry.

It can only be prevented by adding medicine to the pot. Beijing Full automatic fuel oil steam generator Adding drugs to the boiler can further soften the water quality, making up that the softening water equipment cannot replace silicon, sulfur and heavy metal ions and anions, so that impurities such as suspended solids, water slag and scale in dissolved water have good looseness and fluidity, and then the impurities are discharged by sewage, thus preventing scale. The water treatment method is carried out in the pot, so it is called water treatment method in the pot. small-scale Full automatic fuel oil steam generator how much Therefore, boiler water treatment actually includes water treatment of feed water and quantitative feeding treatment in the boiler. Water treatment should only be carried out without adding drugs. The boiler water index basically does not meet the specified requirements, and the boiler cannot operate under good water quality. This is also the main reason for the softened water device. The softened water is also qualified, and the boiler will also be polluted.

The hardness of water is mainly formed and expressed by calcium and magnesium, so cation exchange resin (water softener) is generally used to replace Ca2+and Mg2+(the main component forming scale) in the water. With the increase of Ca2+and Mg2+in the resin, the efficiency of the resin to remove Ca2+and Mg2+gradually decreases. Beijing Full automatic fuel oil steam generator When the resin absorbs a certain amount of calcium and magnesium ions, it must be regenerated. The regeneration process is to wash the resin layer with salt water in the salt tank to replace the hardness ions on the resin. With the regeneration waste liquid discharged out of the tank, the resin will resume its softening and exchange function. small-scale Full automatic fuel oil steam generator how much Because the hardness of water is mainly formed by calcium and magnesium and represents that the hardness of water is mainly formed by calcium and magnesium and represents the principle of sodium ion exchange softening treatment, which is to exchange the hardness components Ca2+and Mg2+in the water with the Na+in the resin by passing the raw water through the sodium cation exchange resin, so as to absorb Ca2+and Mg2+in the water and soften the water.

The waste heat boiler is composed of drum, movable smoke hood, feeding pipe groove, oxygen lance mouth, furnace mouth section flue, inclined section 1 flue, inclined section 2 flue, last section 1 flue, last section 2 flue, nitrogen sealing device and nitrogen sealing plug, manhole, micro differential pressure tapping device, flue support and hanger. Beijing Full automatic fuel oil steam generator Unlike conventional boilers, waste heat boilers do not produce combustion process and do not have combustion related equipment. Essentially, they are just gas water/steam heat exchangers. The waste heat boiler is divided into six circulation loops. Each circulation loop is composed of downcomer and riser. The feed water of each section of flue is introduced from the drum through downcomer to the lower header of each flue, and then enters into each heating surface. The water passes through the heating surface and generates steam into the header, and then is introduced into the drum through the riser. small-scale Full automatic fuel oil steam generator how much The needle tube waste heat recovery device is a special high-efficient energy-saving product specially designed for waste heat recovery of flue gas. The heat recovery boiler uses needle shaped tubes to strengthen the heat elements to expand the heating surface. The heating surface on the water pipe smoke side can be greatly increased. At the same time, the smoke will form strong turbulence when passing through the needle shaped tube surface, which will improve the heat transfer efficiency and reduce the soot accumulation.

When the boiler is shut down, the temperature of the heat transfer oil can be reduced to below 70 ℃ before the hot oil pump is shut down. In case of sudden power failure, extinguish the fire immediately, and then implement the operating procedures. Otherwise, the furnace tube will be burned out and the loss will be large. According to the type of heat transfer oil boiler, heat transfer oil shall be reasonably selected to prevent overheating. Beijing Full automatic fuel oil steam generator When purchasing unqualified heat transfer oil, do not save money or mix heat transfer oil indiscriminately. Otherwise, the consequences will be very serious. Prevent the oxidation of heat transfer oil. The strict heat transfer oil is more than 50 degrees in contact with the air, which will make the heat transfer oil crack. Its speed is amazing, and the consequences are relatively serious. After normal operation, the test crew needs to close the exhaust valve on the auxiliary exhaust pipe. After 6 months of use, the heat transfer oil must be sampled and tested according to the instructions. If problems are found, the heat transfer oil must be replaced immediately. small-scale Full automatic fuel oil steam generator how much However, it should be noted that different types of heat transfer oil should not be mixed. The circulation speed of the heat transfer oil should not be less than 1.5m/s. Due to the excessive temperature difference between some entrances and exits, the original design requirements were destroyed, the heat transfer oil could not maintain the original circulation state, the boundary layer became thicker, and the thermal resistance became larger, making the furnace wall exceed the oil film temperature, leading to carbon deposition, cracking, polymerization, coking, and even burning through the furnace tube.

The manufacturer of the pneumatic water tank shall hold the pressure vessel manufacturing license or registration, and have a sound quality management system and system. Beijing Full automatic fuel oil steam generator The purchased parts of the equipment must have the product certificate and pass the entrance inspection before use. The pneumatic water tank, water pump unit, electrical components and other components of the three-dimensional elastic filler manufacturer's equipment shall be assembled and used after passing the inspection. The equipment assembled on site can be used to inspect the performance of the whole machine on site. The production license issued by the relevant department shall be held. small-scale Full automatic fuel oil steam generator how much When selecting this product, requirements shall be put forward for the following items: equipment composition, equipment classification, equipment working pressure, equipment design flow, specification and quantity of air pressure tank, equipment data, and sanitary requirements. The overall structure of equipment, water pipe, gas pipe and electrical circuit shall be arranged reasonably, and the manufacturer of single hole mold aerator shall reserve space for device maintenance to facilitate operation. The pipeline of the equipment shall be equipped with a safety valve, and the opening pressure of the combined packing manufacturer shall not be greater than 1.1 times of the working pressure. The equipment shared by fire fighting and living (production) shall have a separate fire water outlet.
